4,1-Benzoxazepin-2-one derivatives represented by the formula (I) :
, wherein R1 stands for hydrogen atom or an optionally substituted hydrocarbon group; R2 and R3 independently stand for hydrogen atom, an optionally substituted lower alkyl group, an optionally substituted phenyl group or an optionally substituted aromatic heterocyclic group ; X stands for a bond or a spacer having the chain length of 1 to 7 atoms ; Y stands for an optionally esterified or thioesterified carboxyl group, an optionally substituted hydroxyl group, an optionally substituted amino group, an optionally substituted phenyl group, an optionally substituted carbamoyl group or a N-containing heterocyclic residue having hydrogen atom capable of being deprotonated ; provided that, when X is methylene and R1 is not an alkyl group having carbon atoms of more than 4, Y is neither carboxyl group nor alkoxycarbonyl group ; and the ring A may optionally be substituted, or salts thereof, which are useful for inhibiting squalene synthetase and fungal growth.
4,1-苯并氧氮杂卓-2-酮衍生物,由式(I)代表:
其中 R1 代表氢原子或任选取代的烃基;R2 和 R3 分别代表氢原子、任选取代的低级烷基、任选取代的苯基或任选取代的芳香杂环基;X 代表键或链长为 1 至 7 个原子的间隔物;Y 代表任选酯化或硫酯化的羧基、任选取代的羟基、任选取代的氨基、任选取代的苯基、任选取代的氨基甲酰基或含有能被去质子化的氢原子的含 N 杂环残基;条件是,当 X 为亚甲基且 R1 不是碳原子数超过 4 的烷基时,Y 既不是羧基也不是烷氧羰基;并且环 A 可以任选被取代,或其盐类可用于抑制角鲨烯合成酶和真菌生长。
